Force feedback device

Abstract

A force feedback device includes a platform, an elastic apparatus, a drive apparatus, a sensor, a control card, and a software system. The software system is configured to process data of a game and transmit data to the control card. The control card is configured to control the drive apparatus to drive the elastic apparatus. The elastic apparatus is configured to control the platform. The sensor is configured to sense the distortion of the elasticity apparatus to know the working status of the platform and transmit data of the distortion to the control card. The control card is configured to process the data of the distortion and transmit it to the software system to change information of the game. The force feedback device has bidirectional data and force transmission.
